Time-dependent light-matter coupling and quantum dynamics

Abstract: In this thesis, two quantum dynamical system’s of one and two qubits coupled to a field mode confined in an optical cavity have been studied. Within the Jaynes- and Tavis- Cummings model, the dynamics of the corresponding light-matter interaction was defined in terms of the system’s coupling constants. From the setup of the system, the qubits flying through the cavity, the final state of the system could be adjusted by changing the dynamics via the time-dependent coupling constants. In the two qubit system, it was found that the entanglement between the qubits could be modified by the dynamics to obtain a maximal entanglement in the final state. These findings provides a starting point of how entanglement can be achieved via quantum dynamical light-matter interaction.
